WATER-BOTTLE STOPPER.

SPECIFICATION forming part of Letters Patent No. 787,118, dated April 11, 1905.

Application filed July 19, 1904. Serial No. 217,173.

l-Ie it known that we, MAXIMILIAN CuAnLns Seuwuiyuirr, residing at ll'est Hoboken, in the county of l'l'udson and State of New Jersey, and llnxuv P. liruxifr, residing in the city, county, and State of New York, both citizens of the United States. have jointly invented certain new and useful Improvements in lVater-Bottle Stoppers, ot' which the following is a specilication.

This invention aims to provide certain improvements in the construction of stoppers for water-bottles or the like, whereby their manufacture is facilitated and whereby especially the application of a washer thereto is facilitated.

A fastening device, preferably of metal, is tirst connected to the washer and is then introduced by a very simple movement into place upon the stopper-body, where it prevents accidental removal of the washer. The combined washer and fastening' device constitute a separate article of manufacture adapted to be readily mounted upon the stopper-body. ln this way the construction of the complete stopper is considerably simplilied and cheapened.

The accompanying' drawings illustrate embodiments of the invention.

Figure l is a side elevation otl a stopper in the usual socket. Fig. 2 is an underside plan view ot' the same. Fig. 25 is a central section at right angles to Fig. l. Fig. is an under side plan view of Fig. 3 with the washer cut otl. Fig. 5 is a view similar to 3, showing the manner of applying the fastener to the body of the stopper. Figs. 6 and 'T are underside plan views illustrating another form of the invention with the fastener in its linal position and in the act of being' introduced, respectively. Figs. 8 and 9 are similar views of another form of the invention. Figs. IO and Il are similar views ot' still another form of the invention. Figs. IQ and 13 are similar views of still another form ot' the invention. Figs. Il, l5, and IG are views similar to Figs. 3, lf, and 5, illustrating' still another form of the invention, in which the retainer is ot' flexible and elastic material. VIn Figs. G to 13 and in Fig. l5 the washer is cut otl'.

Referring to the drawings, the stopper comprises a screw-tln'ezuled body portion A, upon the top of which are mounted a head and thumb piece or any other suitable means for screwing it into place. 'lhe stopper screws into a socket B, having at its lower edge an inward flange (l. A washer l), of rubber or the like, is compressed between the bottom of the stopper and the flange t l ol the socket; when the stopper is screwed home. ',lhe novel feature ot' the invention is in the manner ot' attaching the washer l) to the body of thestopper or of any similar stopper. 'lhe body ot' the stopper comprises the screw-tlu'ezuled vertically-extending portion anda horizontal bottom portion,through which there is an opening leaving around the edge a l'lange which may be of various shapes and dimensions. The washer is connected to a retainer,aml the sha pes` ot' the flange and the retainer are such that the retainer in one position or another maybe introduced within the l'lange and then turned to a position in which it cannot be withdrawn. For example, in Figs. 3, i, and 5 the tlange E is circular, while the retainer F oblong and is attached to the washer l) by a rivet at the center. The length of the retainer is greater than the diameter of the opening within the flange. However, by bonding the washer between the thumb and linger in the manner indicated in Fig. 5 and tilting the retainer it may be introduced endwise within the flange and then brought back to a horizontal position, so as to extend over the edge of the flange at its opposite ends. The rubber washer l) holds it with a suflicient pressure against the inner face of the flange, and it cannot be accidentally witlulrawn. It is preferred to provide a stop Il, consisting ot a strip of metal extending across the opening and a slight distance above. it, so as to prevent the washer from being pushed through the hole in the bottom of the body.

ln Fig. 6 the l'lange E is provided withinward extensions, between which are four open spaces o'l greater diametral length than the diameter of the retainer, which, in this case, is a circular disk E. The retainer can, by slightly bending the washer in the manner shown in Fig. o, be introduced obliquely IOO through either of the pairs of open spaces (see Fig. 7) and then shifted to a central p0- sition, where it will be held against removal, the rubber washer linsuring a suflicient friction of the retainer against the inner face of the flange.

Figs. 8 and 9 illustrate a reversal of the construction shown in-Fig. 3. The flange E2 has an oblique opening through which a circular retainer F2 is introduced by a lateral movement, as explained in connection with Fig. 7.

In the construction shown in Figs. 10 and 11 the flange E3 has a small circular opening at the center with two diametrically-opposed slits, so as to give a clear space greater than the diameter of the circular retainer F3, so that the latter may be introduced in the manner indicated.

According to Figs. 12 and 13 the iiange EA1 is formed with a keyhole-shaped opening. The retainer F'l is just small enough to pass through the enlarged end of the opening, after which it is pushed laterally, with the washer and rivet G, of course, to a central position, where it is held by friction.

According to Figs. 14 to 16, the retainer F5 is of rubber or similar eXible and preferably elastic material and is introduced by squeezing its edges together in the manner indicated in Fig. I6. The iiange and the retainer F5 are preferably made circular in this construction. The washer D and the retainer F5are connected by a rivet G just as in the other constructions shown.

Though we have described with great particularity of detail certain embodiments of our invention, yet it is not to be understood therefrom that the invention is limited to the specific constructions disclosed.

Various other constructions may be made by those skilled in the art without departure from the invention.

What we claim is l. In combination, a stopper-body having an inward flange, a washer, and a separatelyformed fastening device adapted to be passed through the opening within said flange and to engage said iiange to hold said washer over said iange and prevent removal of the washer.

Q. In combination, a stopper-body having an inward flange, a washer, and a rigid fastening device adapted to be passed through the opening within said flange and to engage said flange to hold said washer over said flange and prevent removal of the washer.

3. In combination, a stopper-body having an inward flange, a disk of packing material forming a washer, and a metal fastening device connected to the center of said disk and adapted to be passed through the opening within said iiange and to engage said flange to hold said washer over said flange and prevent accidental removal of the disk.

4. In combination, a stopper-body having an inward ange, a washer, a separatelyformed fastening' device adapted to be passed through the opening within said flange and to engage said iiange to hold said washer over said iange and prevent removal of the washer, and a stop within said body for limiting the inward movement of the fastener.

. 5. In combination, a stopper-body having an opening through its bottom leaving an inward iange around the edge, a disk of packing material extending over said ange to form a washer, and a metal fastening device connected to the center of said disk, the relative dimensions of said opening and said fastening device being such that the latter can be passed through the opening in one positionV and is held from withdrawal in another position.

6. In combination, a stopper-body having an opening through its bottom leaving afiange E around the edge, a disk vD of packing material extending over said iiange to form a washer, and a metal fastening device F ri\ eted to the center of said disk having a width less than that of said opening and a length greater than that of said opening, whereby4 the fastening device may be tilted and passed through said opening.

In witness whereof we have hereunto signed our names in the presence of two su bscribing witnesses.
